Commands and Tips for Third-Party Devices
CTC Analytics PAL Sampler Commands

In addition to  General Device Commands, the CTC PAL Samplers support the following commands and properties (please note that the display Filter level determines which commands and properties are displayed):

Description

Busy

Busy/Idle

Expert

Indicates whether the device driver has sent all commands or whether execution of a command is complete
(read-only).

CPUSerialNo

-

Expert

Indicates the CPU serial number of the connected sampler
(read-only).

DeviceState

Ready/Busy/
Init(Error)/Unknown

Normal

Indicates the current device status (read-only).

StatusDescription

-

Normal

Indicates the current action of the sampler. If no action is being performed, Idle is displayed
(read-only).

Syringe

-

Normal

Indicates the installed syringe type (read-only).

 

Inject properties

Description

AgitationOffTime

0-99 s or Default*

Normal

Specifies the period during which the agitator is idle.

AgitationOnTime

0-99 s or Default*

Normal

Specifies the period during which the agitator is active.

AgitationSpeed

Depends on the agitator; indicated in rpm.
Special values: Off and Default*

Normal

Sets the agitation speed in revolutions per minute and starts the agitator (Off deactivates the agitator).

AirVolume

Depends on the volume of the installed syringe; indicated in µl.
Special value: Default*

Normal

Specifies the air volume to be drawn for the Inject and/or WashWithSample commands (in LC_Inject and GC_Inject modes).

FillSpeed

Depends on the minimum and maximum speed of the installed syringe; indicated in µl/s.
Special value: Default*

Normal

Fill speed for the preparing fill strokes for the Inject and/or WashWithSample commands.

FillStrokes

0-99 or Default*

Normal

Number of preparing fill strokes for the Inject and/or WashWithSample commands (in all injection modes except Custom).

FillVolume

Depends on the syringe volume; indicated in µl.
Special value: Default*

Normal

Fill volume for the single piston strokes (for the Inject command in GC_Inject mode and for the WashWithSample command).

GCCycleTime

0 - 1440 min

Normal

Specifies the run time for the GC between two injections. In sample programs, this value must be set prior to the Inject command

IncubationTime

0 - 1440 min

Normal

Specifies the incubation time for the sample.
In sample programs, this value must be set prior to the Inject command (only in HS_Single injection mode).

IncubTimeOffset

0 - 1440 min

Normal

Additional incubation time with respect to the previous sample in a sequence. This value can be set only once per sequence (only in HS_Progr injection mode).

IncubTimeStart

0 - 1440 min

Normal

Incubation time for the first sample in a sequence. This value can only be set once per sequence (only in HS_Progr injection mode).

InjectMode

LC_Inject Custom (for LC),
GC_Inject/HS_Single/HS_Progr/
Custom (for GC)

Advanced

Injection mode. In sample programs, this value must be set prior to the Inject command.

Injector

List of all injection objects for the installed PAL

Normal

Injector to be used for the Inject and/or WashWithSample commands (for all injection modes except Custom). The setting is ignored in Custom injection mode.

InjectSpeed

Depends on the min. and max. speed of the installed syringe;
Special value: Default*

Normal

Syringe speed in µl/s for injections to the sample loop/GC inlet
(in LC_Inject, GC_Inject, and HS_Single modes).

PostInjectDelay

0 - 99000 ms or Default*

Normal

Time between the injection and the removal of the needle from the injector (in LC_Inject, GC_Inject, HS_Single, and HS_Progr modes).

PreInjectDelay

0 - 99000 ms or Default*

Normal

Time between insertion of the needle into the injector and injection of liquid into the sample loop (GC inlet) (in LC_Inject, GC_Inject, HS_Single, and HS_Progr modes).

PreparationTime

0 - 1440 min

Normal

Preparation time. This value is set in HS_Single mode at the start time of a new sample (read-only). Corresponds to the remaining incubation time of the running sample (marked green), i.e., the time until the sample is injected.

PullupDelay

0 - 10000 ms or Default*

Normal

Indicates the delay time between drawing the liquid into the syringe and dispensing the volume that is not required (in GC_Inject mode and for the WashWithSample command).

Tray

List of all tray objects of the installed PAL

Normal

Tray to be used for Inject (for all injection modes except Custom).

Note: If you select a different tray, the TrayName property is updated automatically.

TrayName

String

Normal

Indicates the name of the current tray

Note: If you select a different tray, the Tray property is updated automatically.

 

*  Note: 

For the Default parameter, the default value set by CTC on the respective device is used.
